Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12078, here are decompositions:

5 + 12073 = 12078
7 + 12071 = 12078
29 + 12049 = 12078
37 + 12041 = 12078
41 + 12037 = 12078
67 + 12011 = 12078
71 + 12007 = 12078
97 + 11981 = 12078

Showing the first eight; more decompositions exist.
